In case you don't know the plot of PORNO HOLOCAUST, a zombie with a very large penis strangles women with it. Good ol' D'Amato.
When you do check out ANTHRO be sure you get the uncut version. This is a love it or hate it film with the majority of people hating it but the gore is the most notorious thing about it. The Shriek Show DVD is uncut but there's a budget release that is the R-rated American cut, which is missing ALL the gore.
